Using farming in a simple two-server clustered environment (using defaults of the 'all' configuration), there appears to be a problem re-deploying applications under JBoss 3.2.7.

The problem does not occur in 3.2.6 or 4.0.x, but occurs in both 3.2.7RC1 and 3.2.7Final.

-If I deploy an application by dropping it into the farm directory on one of the clusters, it deploys fine to both servers and runs as expected.

-If I then delete the file from the farm directory to undeploy it, both servers undeploy the deployment (EAR file containing one servlet and one bean and some precompiled jsps) as expected.

-If I then attempt to redeploy the same EAR file again, by dropping it into the farm directory (as originally done), it deploys on both servers.

-If I then try to access the servlet, it fails with ClassNotFound exceptions being thrown.

Given that the same application doesn't exhibit this behaviour on either 3.2.6 or 4.0.1SP1, it appears to be a bug in 3.2.7.. Any suggestions to workaround this would be appreciated.

NB: Not using the clustering features - just a standalone default server - JBoss is able to redeploy this application and it works no problems. It appears to be a problem with farming.
